In late July, Jacob O'Connor noticed something floating in the backyard pool before realising it was his younger brother, who had crept outside through open doors, drowning face down in the unfenced area.

In the video, the actor stated that Jacob pulled his brother Dylan out of the pool where he was lying face down and started administering CPR and chest compressions.

He said: 'There was an quake, then it caused a tsunami and then there was a daughter that was drowning and he had to get her out and he did the same thing'. Johnson took to social media to praise Jacob O'Connor, after the Detroit-area youngster helped saved his two-year-old brother Dylan from drowning. "I now need to shake young Jacob's hand".

But there might be more value to those movies than just the visuals and excitement.

"You're a real life hero", The Rock wrote in one of four tweets about Jacob's actions.

It was then that Jacob went to see what was going on.

Dylan had been face-down in the water for nearly a minute.

Jacob then approached his grandmother, Ellen Vial, and told her what had happened. She has now installed double locks on her screen doors, so if she is going to be out of the room for minute she can lock them.

Dylan was discharged from the hospital the day after the incident with no apparent neurological damage, O'Connor said.

"Jacob, I'm so proud of you, so much so I have got to meet you. Hopefully, your little 2yr old brother, Dylan is well enough to fly because I wanna meet him too", said the father of two daughters.
